This invention comprises improvementsin appliances for delivering lgranular material in measured quantities by volume.

This invention comprises a machine particularly applicable for delivering measured quantities of meat into a pie casing.

According to the c present improvements, the machine comprises a rotating drum member which is recessed on .diametrically oppoio site sides and in which two 'pistons form the bottoms of the recesses, the pistons being J connected on the outside of the rotating member by means of an adjustableI link which engages pins carried by the pistons, such pms passing through slots in the walls of the recesses. lhe rotating member is intermittently rotated by means of a disc having radial slots whichare engaged by a pin.

mounted on a rotating member, this arrangement bein characterized in that the spindle carrying ie rotating member is geared to the said disc so that an increased rotary movement is given to the said rotating member and also characterized in that the said disc is positively held at the end of each forward movement. The pistons are positively moved to eject the material by means of the pins, connected to the pistons, which pass through slots in the side of the rotatin member, with which pins means co-act, in ependently of the adjusting means for the position of the pistons, to eject the meat or the like from the recesses.

The meat is placed in a ho per and is fed into the recesses by means o ascrew which is detachably connected to driving mechanism located at the upper en d of the hopper. A stirrer is also mounted co-axially with the said feeding screw and is driven in the reverse direction. The meat is directed in a downward direction into pie casings by means of a roller or rollers or other downwardly moving member which isV located behind a scraper.

Referring tothe drawings, the revolving drum 1 has a cylindrical recess 2 formed diametrically through the drum. Two pistons .3 and 4 are connected together and are adapted to reciprocate in the recess 2, the ends of the pistons thus forming the bottoms of recesses in diametrically opposite sides of the drum. The pistons move in unison and when one piston is fully in, the other piston is fully out. The pistons are connected together by means of one link 5, the upper end of which is fixed to the pin 6 passing through the piston 3, whilst the other end is adjustably connected to the pin 7 carried by the piston 4. A slot 8 in the link 5 (Figure 3) receives the pin 7, the end of such pin being carried by a block 9 clamped to the link 5 by means of the A feed hopper 25 is located on the top side 95 of the drum 1 so that when one receptacle is moved to register with the mouth of the hopper the piston forming the bottom of such receptacle is at its lowest position in the receptacle to receive the required quantity l of meat. When the drum lis rotated through one hundred and eighty degrees this latter full receptacle is placed over a pie casing, and the piston forced outwardly to e]ect the meat into the pie casing. As the two plstons are connected together the other receptacle which is moved in register with the hopper will be re'ady to receive the next charge of meat, as the piston in such receptacle will -have been moved to its lowest position in the receptacle when the other piston is moved outwardly to eject the meat.

The drum is intermittently rotated by way of the shaft 16 through one hundred and eighty degrees so that time is allowed when the drum is stationary for the meat to be fed into the top receptacle. The device for effecting this comprises a disc 12 having radial slots 13 which are engaged by a pin or roller 14 mounted on the rotating member 15. Pins or rollers 12a are mounted on the disc 12 between the slots 13 for engagement with the groove 13"* in the tail piece 15, to hold the disc 12 and consequently the drum 1 stationary during the illin of and dischargin from the receptacles. gThe shaft 16 is rotate by means of a worm 17 and worm wheel 18 from the spindle 19, the latter spindle being driyen by a chain drive from the electric motor 20. The shaft 21 carrying the disc 12 carries a gear wheel 22 which drives the drum 1 through the medium of the gear wheels 23 and 24. It will thus be seen that the drum is quickly rotated through one hundred and eighty degrees during a portion of one complete revolution of the member 15, the. re-

mainder of a revolution of such member 15 taking place whilst the drum is stationary. The hopper 25 is mounted over the drum and a member 26 is located between the bottom of the hopper and the periphery of the drum which is a sliding fit over the curved face of the member 26. The lower portion of the hopper 25 is conveniently conical and a cor- "respondingly shaped feeding screw 27 is mounted thereon, the feeding screw being supported by resting on the conical wall of the hopper. The feeding screw is suitably driven and preferably the arrangement is such that the feeding screw may be readily removed for cleaning purposes. A stirrer 28 is also preferably provided for ensuring that the meat or the like will pass down on to the feeding screw. In the arrangement shown, the spindle 29 is driven by chain gearing from the shaft 16, and such spindle 29 is detachably engaged with the end of the spindle 30 carried by the casting31. This casting 31 also carries the bevel wheels 32, 33, and 34 so that such casting and the bevel wheels may be removed as a complete unit. The spindle 37 of the feeding screw has a square end for engaging the spindle 35 of the bevel wheel 32. The stirrer 28 is carried by the sleeve 36 which is slidably engaged over the spinfacilitates cleaning operations.

dle 37, and the end of such sleeveth'as a square end for engaging in a squareirecess in the boss of the bevel wheel 34. The casting 31 is fined at one end by meansof Va pivoted lever 39 or in any other convenient manner. When the lever 39 is released, therefore, the casting 31 can be lifted away so that the shaft 30 is slidden out of engagement with the shaft 29and With the bevel wheels out of engagement with the sleeve 36 and spindle 37.

The stirrer and feeding screw can then be liftedv from the feed hopper which greatly The feed spindle is therefore continuously driven and in order therefore to allow for escape of meat when a receptacle is not under the feed hopper, ribs 40 are provided on the sides of the hopper to thereby form channels by which meat can escape upwardly. The pistons would normally be forced downwardly by the meat fed into the top receptacle and by the weight of the pistons, but preferably positive means are provided for moving the pistons downwardly, such means conveniently comprising a lever 41 which is normally pulled upwardly by means of a spring 42 to bear against the drum shaft 1. This lever is depressed by means of an arm 43 mounted on the shaft 16 a pin on which engages the tail iece 41a of the lever 41. The lever is time to be depressed after the drum has been rotated into the position shown by Figure 1 with the lower receptacle in position for discharging the contents. The lower end of the lever 41 bears on the end of the pin 7 projecting from the side of the drum 1 (opposite to the side of the drum on which the link 5 lies) for discharging the lower receptacle. Any other suitable means may however be used for this purpose.

To prevent meat clinging to the drum a scraper 44 is fixed to the machine and adapted to bear on the drum in the position shown by Figure 1 to thereby prevent any meat or the like being carried round by the drum. The meat will have a tendency to be carried rearwardly and a roller or rollers 45 is or are provided for causing the meat to slide downwardly and also to prevent any lodgment or collection of meat, the rollers being rotated downwardly in the same direction by means of a chain 47. A scraper 46 is also spring pressed against the roller or bottom roller 45 to keep such roller clean. The outer edges of the recess 2 form a cutter for shearoff the meat when the receptacle has beenl In? fil ed from the hopper.

' The table 48 is rotatably mounted on the` bed of the machine to be intermittently rotated so that pie casings are successively placed in position for being filled. A guard lll) 49 may be fitted to prevent materialv being thrown from the recesses when the drum is rotated.
